Illaddtagslaterlol Stories

a funny little story about the seven halfbloods (and some) from the heroes of olympus get a letter that they need to come to hogwarts to protect a certain wizard. inspired by @kindesthearts, who seems to have discontinued their version of the story. It was a fun prompt, so I would like to write my own version!:) (all characters belong to j k rowling and rick riordan, headcannons excluded)
